Sharpness Cont... 3

Sharpness at 14mm

The sharpness tests for this review were carried out using a real-world subject rather than a test chart. The LUMIX G VARIO 7-14mm F4.0 ASPH lens was attached to a Panasonic Lumix DMC-GH2 compact system camera, which in turn was mounted on a sturdy tripod. The self-timer was used to avoid any vibrations from pressing the shutter release. Slight tonal changes are due to slight changes in natural light during the session.

Centre sharpness at 14mm is best at f/5.6, while the edges are acceptably sharp from f/4 to f/8.
